Use helper function getIndexForValue in MulticastRoutingCoordinator.

The SparseArray.indexOfValue() uses == to compare values,
MulticastRoutingCoordinator uses SparseArray with String type values,
and the indexOfValue function would sometimes return -1 when looking for
a value in the SparseArray.

Added a helper function getIndexForValue in CollectionUtils to get index
by comparing values with equals, and used this function in MulticastRoutingCoordinator.

Updated
MulticastRoutingCoordinatorServiceTest#testMulticastRouting_applyConfigNone_removesMfc
test case to use copies of interface names when updating the multicast
configs, so the test would fail without this fix.

Test: atest NetworkStaticLibTests:com.android.net.moduletests.util.CollectionUtilsTest#testGetIndexForValue
atest android.net.connectivity.com.android.server.connectivity.MulticastRoutingCoordinatorServiceTest#testMulticastRouting_applyConfigNone_removesMfc
